Cap Tightener Machine (Servo Retorquer Capping Machine)


The high torque servo retorque capping machine provides stable capping torque. The electronic cap tightener machine’s gearing driven control does not overtighten or loosen caps. Single-head servo retorque capping machine’s capping applicator is the only component that needs to be switched while changing caps, so it can apply to multiple sizes of caps. The production conditions can be adjusted in accord with sizes and caps of bottles.

High Efficiency Cap Tightener Machine

Cap tightener machines are suitable for any size of plastic round caps, pump heads, downward pressing caps, duckbilled caps, spray caps, screw caps, round heads and safety caps in many industries. It can apply to the industry of beverage, food, biotech, chemical engineering, pharmacy, and machinery. Using human-machine touch interface to set up the capping torque, and the applicator can immediately tighten the caps right after it presses downward, causing no wrist injuries due to repeated movements. Only applicators are changed when changing over, and the adjustment of the speed needs no tools. Cap tightener machine can work efficiently for the best productivity. The high torque capping machine not only can operate by itself, but also upgrade to an automatic package line of filling and capping by connecting a filling machine. Therefore, it is an economical machine with good capping quality.
